Lin Chen came home from school and saw Lin Xi playing a road RV escape game. Lin Chen had no intention of paying attention to her, so he walked straight into the room and threw himself on the bed. Not long after, he fell into a deep sleep. In the middle of the night, Lin Chen woke up from hunger. He walked out of the room in the dark and found his sister still lying in front of the computer desk. The computer screen was dimly lit, and there was a half-eaten bucket of instant noodles beside the table. "You're so lazy. If I don't want to cook, you have to make do by yourself." Lin Chen muttered and walked towards the kitchen, but out of the corner of his eye, he saw a red emergency prompt popping up on the computer screen: "The end of the world is coming, and the world has entered survival mode. Players are asked to start the RV immediately." He subconsciously reached out to turn off the prompt. As soon as his finger touched the mouse, he suddenly felt a violent dizziness. His vision went dark and he fell to the ground.
